The P5AD2-E Deluxe is one of the most comprehensive ASUS AI Proactive series motherboards. Featuring dual RAID systems, gigabit Ethernet LAN, 1394a, and the most advanced PC technologies from the Intel 925XE chipsets, the P5AD2-E Deluxe is the best choice to build a server at home. With its unsurpassed performance, the P5AD2-E Deluxe also works perfectly as a high-end gaming machine or a task-intensive workstation.

Intel EM64T Intel EM64T (Intel Extended Memory 64 Technology) allows processors to run newly written 64-bit code and to access larger amounts of memory, which delivers exceptional graphic performance and higher data processing speed. Digital media applications can take advantage of Intel EM64T in high quality video and audio processing as well as 3D rendering.

Dual-Channel DDR2 533DDR2 is the next generation memory technology to replace the current DDR. With initial speeds from 400 and 533MHz, DDR2 memory provides bandwidth up to 4.3GB/s. Doubled by the dual-channel architecture, the widest memory bus bandwidth 8.6GB/s is achieved on this motherboard.

PCI Express ArchitecturePCI Express is the latest I/O interconnect technology that will replace the existing PCI. With a bus bandwidth 4 times higher than that of AGP 8X interface, PCI Express x16 bus performs much better than AGP 8X in applications such as 3D gaming. PCI Express x1 also outperforms PCI interface with its exceptional high bandwidth up to 500MB/s. The high speed PCI Express interface creates new usages on desktop PCs e.g., Gigabit LAN, 1394b, and high-speed RAID systems.

Stack Cool? Cooler Overclocking and Quieter Operation!Heat causes instability and shortens system lifecycle, and motherboard power circuitry is a major thermal source. The patented Stack Cool? technology utilizes a mini PCB stacked against the main PCB to conduct heat away from power components, resulting in a 10° Celsius reduction. And voila! Cooler overclocking, quieter fan operation, greater stability and longer system life without you doing a thing.

AI NOS? Boost performance when you need it the most!Applications such as 3D games and video editing demand a huge chunk of system resource. Inject "nitrous oxide" into your CPU! The patented AI NOS? (Non-delay Overclocking System) technology intelligently detects system load and automatically boosts performance for the most demanding tasks. Unlike other dynamic overclocking techniques, AI NOS? reacts much faster to satisfy your unending need for speeds.

AI NET2 Diagnose LAN connection before entering OS!Network problems are often caused by bad cable connection. AI NET2 remotely detects cable connection the second you turn on the system, and any faulty connections are reported back up to 100 meters at 1 meter accuracy.

High Definition AudioEnjoy high-end sound system on your PC! The onboard 8-channel HD audio (High Definition Audio, previously codenamed Azalia) CODEC enables high-quality 192KHz/24-bit audio output, jack-sensing feature, retasking functions and multi-streaming technology that simultaneously sends different audio streams to different destinations. You can now talk to your partners on the headphone while playing a multi-channel network games. All of these are done on one computer. The Dolby Digital Live technology from Dolby Lab encodes the multi-channel audio source into AC-3 bit-stream and outputs it to S/PDIF port in real time.

S/PDIF-out on Back I/O PortThis motherboard provides convenient connectivity to external home theater audio systems via an optical or coaxial S/PDIF-out (SONY-PHILIPS Digital Interface) jack. It allows to transfer digital audio without converting to analog format and keeps the best signal quality. Max. 8 USB 2.0 ports supportsUSB 2.0 is the latest connectivity standard for next generation components and peripherals. Backwards compatible with current USB 1.1 peripherals, USB 2.0 delivers transfer speeds up to 40 times faster at 480Mb/s, for easy connectivity and ultra-fast data transfers.

Multi-language BIOSThe multi-language BIOS allows you to select the language of your choice from the available options. The localized BIOS setup menu helps you configure your system easier and faster.

ASUS CrashFree BIOS2The CrashFree BIOS2 feature now includes the BIOS auto-recovery function in a support CD. Users can reboot their system through the support CD when a bootable disk is not available, and go through the simple BIOS auto-recovery process. ASUS motherboards now enable users to enjoy this protection feature without the need to pay for an optional ROM.

C.P.R.(CPU Parameter Recall)When the system hangs due to overclocking failure, there is no need to open the case to clear CMOS data. Just simply restart the system, the BIOS would show the previous setting and then users can amend the CPU setting again.
